Spell out in first use then use acronym for the CERN Courier

Use minimal capitalisation. A heading starts with a capital, but other words should not be capped up, unless they are proper nouns. If in doubt, choose lower case.

Exceptions include: our Sun, Earth (the planet), and our Solar System, Universe and Moon, but not other suns, solar systems, universes and moons, or earth as in soil.

Use a capital letter when you are writing the names of people, languages, places and words relating to them:

not carpark

CERN Accelerator School

CERN Axion Solar Telescope

CERN Control Centre

Cold dark matter

Spell out in first use then use acronym for the CERN Courier

The CERN Document Server.

See video.

Not centimeter. See units.

Use the American spelling only for American organisations and place names:

Centers for Disease Control and Prevention

Rockefeller Center

Otherwise, stick to centre:

The Sun is at the centre of our Solar System.

CERN, the European Organization for Nuclear Research, is the organisation that operates the European Laboratory for Particle Physics. Lots of experiments take place at this laboratory.

Stick to the official title "European Organization for Nuclear Research" for CERN websites. 

Use the acronym CERN in the singular: 

CERN offers student work placements (not "CERN offer student work placements")

Formerly the CERN Computer Centre, the CERN Data Centre (CDC) forms Tier-0 of the Worldwide LHC Computing Grid (WLCG). 

The change was made to avoid confusion with the CERN Control Centre (CCC). 

not chairman, chairwoman or chairperson

See gender neutrality

no italics

Chemical compounds and alloys should be hyphenated, but the elements should not be capitalised:

The current in the dipole magnets is carried by cables made of niobium-titanium (NbTi).

Not Cerenkov. Though Cherenkov is a somewhat clumsy anglicisation of the original Russian, the "Ch" ensures unambiguous pronunciation.

CERN Health Insurance Scheme

CERN Internet Exchange Point

CLIC Detector and Physics study

Cosmic microwave background
